在下载了Qualcomm的Hexagon SDK 351版本之后，想跑里面的examples，然后参照文档的说，比如在examples/common/sobel3x3_v60目录下面，先执行了SDK根目录下面的setup_sdk_env.cmd，然后执行make tree V=hexagon_Debug_dynamic_toolv82_v65编译命令，结果编译错误，输出如下错误log，

make[1]: *** [hexagon_Release_dynamic_toolv72_v60/atomic_q] Error 1
粗一看，显然是缺少了对libpthread.so的依赖，第一反应就是想着看能不能添加对这个库的依赖。后面又看了一下编译命令，输入make tree V=hexagon，看到提示支持的variants，发现有不同的toolv，部分如下
hexagon_Debug_toolv72_v60
hexagon_Debug_toolv81_v60
hexagon_Debug_toolv81_v62
hexagon_Debug_toolv81_v65
hexagon_Debug_toolv82_v60
hexagon_Debug_toolv82_v62
hexagon_Debug_toolv82_v65
hexagon_Debug_toolv82_v66
hexagon_Debug_toolv83_v60
hexagon_Debug_toolv83_v62
hexagon_Debug_toolv83_v65
hexagon_Debug_toolv83_v66
然后就想到本SDK中的tools为83版本，于是把编译命令改为make tree V=hexagon_Debug_toolv83_v60，果然，顺利编译完成。然后又试着改为了make tree V=hexagon_Debug_toolv83_v66，也是正确的。所以，出现上述的错误的关键就是在于tools的版本不对，如果这个版本不对，比如我的编译命令中表明需要使用82版本，而本SDK中又只有83版本，然后就找不到对应的tools，所以就会出现这样的问题。
